Question

Nowadays, many children spend hours a day looking at computer screens or other digital (数码的) products. Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome (视力综合症).

Nathan Warford is an optometrist in the US. He says he has seen more children having eye problems. “More children come into my office because their parents have noticed that they have headaches (头疼)or red eyes, or because their degree of short-sightedness appears to be increasing (增加)very fast and they’re worried,” he said.

Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don’t tell their parents, because they don’t want their games or the computer to be taken away. Another part of the problem is that people blink (眨眼睛) less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally(正常地) do in everyday life. If eyes can’t stay wet or are too tired, they will not be protected like normal.

【解析】

试题分析：本篇文章介绍了关于视力保护的问题。现在许多孩子一整天都盯着电脑或是手机屏幕，这些会引起他们得一些眼睛的疾病，医生们称之为“视力综合征”。越来越多的孩子因为头疼，红眼或是近视度数的增加来就医。沃福德医生说道，部分问题是孩子们即使觉得眼部不适，仍然不愿意告诉家长，因为怕被剥夺玩游戏的权利，另一部分原因是他们在看屏幕的时候眨眼的次数减少，大概为平时的三分之一。

1. children come into my office because their parents have noticed that they have headaches (头疼)or red eyes,可以得知，头疼也是眼病的一种其它症状文中没有提到，故选B。

2. children don’t tell their parents, because they don’t want their games or the computer to be taken away.可知，一些孩子不告诉父母是因为他们不想他们的游戏或者电脑被拿走，也就是他们想继续玩电脑游戏。故选B。

3. person who uses a computer or a digital product blinks about a third as much as we normally do in everyday life. 可知，一个看电脑或电子产品的人眨眼的次数大概是正常生活中的三分之一。故选A。
